When air quality is poor Birdie® will drop down until you open your windows and bring it back to life. Simple as that.

 Swiss state-of-the-art CO2-sensor technology 
 Award-winning Danish design
 Made of 100% recycled plastics

Did you know that 90% of your life is spent indoors? — Very often in poor air quality, which increases the risk of asthma, headache, allergies and sleep disorders. (Just in the EU, 80 million homes are estimated to have a poor indoor climate.)

So what to do about it? Experts suggest that one of the best solutions is to simply open the windows. Health Authorities worldwide even recommend you to do it 2-3 times a day. Birdie® is a friendly reminder to a keep healthy indoor climate.

CO2 is a global standard for measuring indoor air quality. There is a certified carbon dioxide (CO2) sensor to measure the concentration of carbon dioxide gas in your home, office or school. Even though there is a ton of particles that can be measured, we believe that monitoring the CO2-level is enough to sustain a healthy indoor climate, as most particles will correlate to CO2 and eventually benefit from opening the windows.

Birdie is the genius design of Danish founders Andreas Kofoed Sørensen & Hans Høite Augustenborg, childhood friends. 

Simply hang the Birdie on the wall ( wall bracket included ) charge via USB-C cable, also  included. Full charge up to 8 months. No sounds, no apps!

Birdie drops when the level of CO2 is higher than 1.000 ppm for more than 10 minutes. When the level of CO2 drops below 800 ppm again the Birdie will return to standing position.
